223 Yet, in June 2013, the NSA found that envelope had been breached by Snowden who deliberately compromised three programs that it used to keep track of terrorist organizations around the world. The first system he divulged, and the one which though it received the most public attention, did the least damage, was what the NSA called the 215 program because it had been authorized by section 215 of the Patriot Act of 2001. This program amassed, the billing records of every phone call made in America that could be used as a data base by the FBI. The idea was that when any foreigner on the FBI’s watch list of terrorists called anyone in the U.S. the FBI could trace that person’s entire chain of telephone contacts to try to determine if he was connected to a terrorist cell. There was, however, a major flaw in this program: it did not cover e- mail and other Internet messaging, which 2013 had largely replaced telephone calls. In addition, terrorist organizations had become fully aware of the vulnerability of telephoning overseas. So although the NSA could cite a handful of early successes that “215” yielded, Snowden’s exposure of it did only limited damage/ But Snowden did not stop with “215.” He next did vastly more damage by exposing the PRISM program also called “702” since it was authorized in 2007 by section 702 of the Foreign Intelligence Surveillance Act.) Since a large part of the fiber cables on which the world’s Internet runs pass through the United States, the NSA was able to intercept 91 percent of its data, including Google searches, social media postings, Skype conversations, messages on Xbox Live, Instant messaging services, tweets on Twitter and e-mails. The CIA and FBI could then track the movements of foreign terrorists. Up until June 6, 2014, terrorist groups presumably were unaware of the NSA’s capacity to vacuum in even encrypted parts of the Internet since they used it for their lethal planning. This ignorance gave U.S intelligence an important ed
